I lifted mine with the moog 784 springs $80 shipped, and 10 minutes in the shop to modify them. I think about 9 turns on the torsion bar bolt in the front. I can't see why you would want to spend any more money than this to lift a vx/trooper.
I can see how building drop brackets would be nice for the vx if running the stock TOD system. I made a set for my RS trooper, but have not for the vx yet.
The money saved on the lift can be used on heavy duty tie rods, which you will likely need if you wheel in the rocks much.
